16 Subject: [PATCH] core: don't use the unified hierarchy for the systemd cgroup
19 Too many things don't get along with the unified hierarchy yet:
21 * https://github.com/opencontainers/runc/issues/1175
22 * https://github.com/docker/docker/issues/28109
23 * https://github.com/lxc/lxc/issues/1280
25 So revert the default to the legacy hierarchy for now. Developers of the above
26 software can opt into the unified hierarchy with
27 "systemd.legacy_systemd_cgroup_controller=0".
